Fuck me weevil, you're making this hard work.
The link you have posted simply tells us what we allready know, that it uses auction style bids and that we have a contractual tie to then buy within the ebay rules.
I totally agree with this, however what the issue here is that I want to ensure the seller is genuine before I part with the money. It is not a case of do I still want the laptop, it is a case of making sure it actually exists before I hand over money. The only way I can do this is by seeing the laptop with my own eyes at the time I hand over the money. The seller did not mention anything about not being able to collect. He simply put payment by cash, cheque or paypal!
Fuck me, I've worked it out, it's you whos selling the laptop is'nt it matey!
